IMPROVEMENT IN ELECTRICAL WATER-GAGES, ALARIVIS, AND` REGISTERS.

Specification forming part of Letters Patent No. 144,540, dated Ncvcnbu 11,1873; ai plication tiled June 24, 1873.

To all whom it may concern:

Be it known that I, CHARLES HEISLER, of the city and county of `St. Louis and State of Missouri, have invented certain Improvements in Electro-Magnetic High and Low Water Indicator, Alarm, and Recorder, of which the following is a specification:

This invention consists in providing the arm of a iloat arranged inside the boiler with a stem passing through a stuiiing-box in the front Aend of the boiler. Said stem carries, Within a suitable case, an oscillating arm, properly insulated, and connected to one pole of the battery. The outer end of said arm carries a small metallic roller, which moves over a series of insulated circuit-breakmg plates, and the oscillation of the lever, caused by the rise and fall of the Water in the boiler, makes and breaks the electric circuit with said metallic plates, which are connected by separate Wires to electro-magnets arranged in a proper case, which may be placed in any part of the building desired. The electro-'magnets of the two outer plates, which indicate, respectively, high and 10W water, operate (when the circuit is open to them) their armatures to disengage a catch or detent of clock-work gearing, and

f allow the same to move, and its movement ring an alarm-bell, and at the same time record, by index-hands moved by the alarm-gearin g, the length of time the water has been allowed to remain too high or low, as the case may be. The electro-magnets of the other circuit-breaking plates, of Which there may be any required number, operate index-hands which are secured to the pivoted armatures of the said electro-magnets. The said hands are arranged in front of a suitably-numbered dial-plate, so that when the circuit is complete to any of the velectro-magnets the indexhand of said electro-magnet will be raised above its number on the dial, so as to indicate the stage of water, and when the circuit is broken the hand will drop back to its number, and, by its Weight, carry the armature away from its electro-magnet. This invention also consists in providing the pivot-stem which is secured to and operated by the iioat with a segmental rack, which operates a small pinion, the shaft of which carries an index-hand, which moves over the face of a proper dial-plate to indicate Figure l is afrontview of my improved de I vice with parts removed. Fig. 2 is a trans verse section of the case containing the circuit-breaking mechanism and the iloat'attachment. Parts of the cases Vare broken away in both figures to show the inside.

A is the boiler, in which is arranged the iioat B, the arm b of which is connected to the stem C, which passes through the stuffing-box a in front of the boiler. The stem C has a tapering boss or collar, C', which fits into the tapering inner end of he stufngbox a.. D is a case, supported in position by its bracket extension D1, which passes over the stungbox a, and is secured in place by the nut a. The stem C passes ythrough the case l)v near its edge, so as to alloT the gage to be used inv confined places-J. e., in boilers having a large breeching in front, which prevents the use of a gage having tl1e stem passing centrally through it, except by placing said gage outside of the breeching, which would be inadf missible, or at least objectionable. E is an oscillating arm, secured to the stem C. Said arm consists of the parts e e1,secured together by bolt e2. The part e is insulated from that of el by a non-conduction piece, e3, arranged between the parts. The part c1.. has secured f to it a spring, E1, to which is secured the lug E2, carrying the shaft of the roller F. The

roller F is held against the collar f of the Shaft by the spring f', the purpose ofthe springs El and f being to keep the'bearings clean and in good conducting order, `and at the same time take up any wear ofthe parts. TheV part e1 of the arm E is connected to one pole of the battery through an insulated wire, h, passing through the cable H into the indicator-case K, from which it passes to one pole of the battery. This course of the wire h through the cable H is not a matter of necessity, as it might pass directly to the battery.` I is a wooden or other non-conducting base, to which are secured a number of metallic plates, 'i l i2 'i3 i4 i5, which are insulated fromeach other, and each of which has separate connection,

. the case K,) to which said plate is connected,

is acted upon, and its armature drawn to said magnet. In case of the plate i, wire j, and magnet L, to set in motion the high-water alarm, and with those, Z1, 71, and L1, to raise -that iinger, M, pointing to number 4 to indicate a height of water almost up to the alarm point. The armatures Z1 Z2, Svc., of the magnets L1 L2, &c., are pivoted, and carry the index-hands M, and when either of them is operated by its electro-magnet it is lifted up from its respective number on the dial-plate m. The armatures Z and Z5 of the magnets L and L5 are connected to the pivoted detents Z6,

which engage stops n n1 of the 'alarm-clock movements N, so that when the armature is attracted to the magnet the clock-work is disengaged and moves by means of a spring or weight to operate the striker n2 of the bell n3. O o are two index-hands for recording the time the water has been allowed to remain either too high or too low, the said hands being moved by the clock-work N. Each electro-magnet L and L5 has its separate clock-work N, so as toact independently, the one, L, indicating 'the water-level to be too high, and the other, L5, indicating it to be too low. The case K, containing the indicating, recording, and alarming devices,77 may be .placed in any part of the building, and the dierent wires may be formed into a cable, H, as shown, or may be separate.

P is a segmental rack, secured to the stem C.V Said rack operates a pinion, p, arranged in proper bearings at the center of the dialplate D2 of the case D. The shaft of said pinion p carries an index-hand, p', which indicates 011 the dial-plate D2 the stage of water in the boiler. This case D is, of course, in the engine-room, and its indications are read by the engineer.

The operation of the apparatus is as fol lows: The float B is sustained at the surface of the water in the boiler A, and, supposing it to be in the position shown, (see Fig. 2,) the level of the water is too high, and the highwater alarm is sounded by the following means: The conducting-wire h, extending from one pole of the battery, is in communication with the part c1 of the arm E, and consequently the electric current passes, through springs E1 and f', roller F plate fi, wire j, helix of magnet L, and wire J to the opposite pole of the battery. This draws down the armatureZ and releases the detent, which allows the alarm clock-work N to run, and the time which it continues to run isregistered by the hands O o. As soon as the water is reduced to the proper level, the arm E is carried over, and the roller F brought in contact with the plate i1, and then the current is established through the wires j1, magnet L1, and wire J, as before, and the armature Z1 raises the hand M of Fig. 4, as the said armature is attractedby the magnet L1. The lowwater alarm is arranged in a similar manner to the high-water alarm, and the current passes through plate Z5, wire j5, magnet L5, and wire J. So the level of the water within certain limits is indicated by the hands of figures l, 2, 3, 4, and the extremes by the alarms.

I claiml. The iioat B, operating a circuit-breaking device, substantially as herein shown, in combination with a recording device, to indicate the length of time the water has been at its high or low stage, as set forth.

2. The combination and arrangement of the float B, arm b, stein C, oscillating arm E, roller F, circuit-breaking plates Z1 Z2 Z3 Z4,wires J h 7'1 jl .i5 j4, arranged in the 'case D, with the electro-magnets L1 L2 LJ L4, armatures Z1 Z2 Z3 Z4, index-hands M, and dial-plate m, arranged in case E, as and for the purpose set forth.

3. The combination and arrangement of the float B, arm b, stem C,oscillating arm E,roller F, circuit-breaking plates z' Z5, and wire J hjj', with electro-magnets L L5, armatures Z Z5, pivoted detents Z6, stops u n1, clock-work N, striker n2, bell a5, and index-hands O o, as and for the purpose set forth.

4. The oscillating arm E e c1, bolt e2, nonconductor piece e5, spring E1, lug E2, roller F, collar f, and spring f', in combination with the stem C, arm b, float B, and circuit-breaking platesi z1Z2,&c., connected to suitable indicating, alarm, and recording devices, as and for the purpose set forth.
